Revive Sleepy Skin

The easiest way to refresh your complexion turns out to be fast — and free. "Simply splash cold water on your face," says Francesca Fusco, M.D., a New York City dermatologist. Coolness constricts blood vessels, giving your skin a smoother, more toned look. Try this while on the go: Tote an atomizer in your purse, such as Avène Thermal Spring Water ($7, drugstore.com).

Slather on a thick, occlusive moisturizer to lock the water into your skin. "With a face balm, any dryness and flakiness will disappear, and wrinkles will be less obvious," says Ranella Hirsch, M.D., a Boston dermatologist. Try Vichy Aqualia Thermal Mineral Balm ($32, drugstores).
